Willpower Is a Scarce Resource
Willpower is a scarce resource with no easy refill, so don't make it the engine. Spend it only where the system can't yet catch you. That's why you design systems.
Willpower isn’t infinite. For me it’s a scarce resource. With no deliberate way to refill it, it eventually burns out. So don’t make it the engine; treat it as a budget to spend carefully.
- Sleep restores a little for most people, but it isn’t the main source: after a rough workday with no better tomorrow, a night’s sleep won’t bring much back.
- Treat it as scarce: spend it only on behaviors that are effective toward the goal but carry a certain coefficient of friction.
- Willpower alone can’t drive every effective habit. That’s exactly why you design systems: when willpower runs dry, your body’s instinct still gets nudged the right way (see Systems Beat Goals and Law 3: Make It Easy).
- Short term you can override temptation with willpower; long term people are products of their environment. Self-control is a short-term strategy, not a long-term one.
- And choose carefully which battles are actually “necessary” to spend willpower on.
Willpower runs out; the system doesn’t. Save it, and spend it only where the system can’t catch you yet.
